I am trying to design a plaque for my first project and I want the corners to be 1.5 inch circular inverted corners and then the edge of the outside to angled. I have played with VCarve but can't seem to find how to do these two operations. I hope to be able to help others on my jouirney once I know what I'm doing.

Not exactly sure what you mean for "outside to angled", but I'll make a guess you just want a chamfered (angled) edge cut around the perimeter. If so, you can use a V-Bit profiled along, or offset from, a perimeter vector. Either create an offset vector from your perimeter cutout vector or just offset the bit when creating the profile toolpath - of course the amount of the offset will depend upon the bit angle and the depth of cut needed for how much of a chamfer you want. There is another way to do it with Pocket v-carving, but the Profile method should do nicely. Your choice.
